Hi Jess,
where abouts in Scotland will you be staying?
There are a number of qualified tandem pilots in Scotland who can take you for an 'air experience' flight, or an instructor could give you a more involved day or half day taster session if you like.
Paragliding is quite weather-dependent, so it's a bit difficult to book it down to a precise day. If you know you're going to be in a certain part of Scotland for a certain period of time, it's probably best getting in touch with an instructor who can give you a tandem experience or taster lesson as you wish. They will keep you informed of the weather closer to the time, and advise you on the best day to go.
It sounds a bit complicated and upredictable, I'm sure. That's part of the beauty of free flight - when it works the way you'd hoped it would, it feels like magic!
Anyway, here's some good instructors, sorted by area:

Good luck, I hope you have a great time!
